This is a good inverter as far as technology is concerned it gives us pure sine wave form AC in its output.Mosfets used are quite better only problem is the charging circuit .
The charging circuits provides much noise on above 200 v input and gets heated up soo quickly last month I charged it on 220 volt and it burnt the relays
Also when we put 800 va load on it mosfets cant bear the current through them and get blasted so I request lumious to use high quality relays and increase the no of mosfets used.
Thanks
